> After the work done in SOLR-14354, all shard requests are sent in the same thread. {{send}} is supposed to be very fast so this shouldn't be a problem, but we currently have {{PKIAuthenticationPlugin}} as a request interceptor/listener, which is called for each shard request to generate and add the authentication token. This part can take a couple milliseconds so with enough shards, there is a noticeable slowdown in distributed search requests.
> We should either speedup PKIAuthenticationPlugin interception (maybe caching? reusing the same token for all shard requests?) and/or making the token generation part run in parallel as it used to.
